This invention relates generally to vehicle Windshield washing systems and in particular to a nozzle structure for such systems.

An object of this invention is to provide an improved nozzle structure for a vehicle windshield washer.

A further object of this invention is to provide a double jet nozzle structure for a vehicle windshield washer capable of being readily mounted on a windshield dividing strip and within the transverse dimensional confines of the strip.

Still another object of this invention is to provide a nozzle structure for a vehicle wind" shield washer which is mountable directlyon the windshield dividing strip such that the installa tion is economically and quickly made with a minimum of defacement to the strip.

A feature of this invention is found in the pro vision of a nozzle for a vehicle windshield washer in which a body member is formed with a transverse fiuid passage having an inlet open to the bottom side of the body member and a pair of tion projected forwardly of the dividing strip.

This head member 18 of a size and shape such Further objects, features and advantages of this invention will become apparent from the following description when taken in connection with the accompanying drawings in which:

Fig. 1 is a fragmentary foreshortened longitudinal sectional view of a vehicle showing a windshield washer, embodying the nozzle structure of this invention, assembled thereon;

Fig. 2 is a fragmentary front view of a vehicle windshield showing the position of the nozzle structure thereon;

Fig. 3 is an enlarged detail sectional view of the nozzle structure taken along the line 3-3 in Fig. 2;

Fig. 4 is an enlarged sectional view taken sub- 1949, Serial No. 111,195

stantially on the line 44 in Fig. 3 with certain parts being broken away for the purpose of clarity;

Fig. 5 is a sectional view taken along the line 5-5 in Fig. 4; and,

Fig. 6 is a rear elevational view of the nozzle body member with parts broken away and other parts in section for the purpose of more clearly showing its construction.

With reference to the drawings there is illustrated in Figs. 1 and 2 a windshield clearing or washing system applied to an automobile hav ing a divided windshield It provided with a center dividing strip or mullion H, an engine cowl if extended forwardly from the windshield, and an instrument panel or dashboard is located rearwarclly of the windshield. The automobile is further equipped with the usual fire wall It and iioorboard it having an upwardly and forwardly inclined portion H which joins with the lower end of the fire wall M.

The windshield washer system includes a pump unit is supported from the floor board portion i"! at a position ad acent to the vehicle clutch ried on the front side of the fire wall It, and the nozzle, indicated generally at 25, which is carried on the center dividing strip ii. The pump unit it is of a diaphragm type and has a on the container 2|. A second flexible conduit 25 is connected between the valve unit 24 and a fluid supply tube 27 for the nozzle 25. A foot operated spring return plunger 28 for the pump unit 48, extends upwardly from the floor board portion I! at a position near the clutch pedal 59. The valve unit 24 is of a construction such that on depression of the plunger 25 fluid under pressure is discharged from the nozzle 25 and on the return or upward movement of the plunger 28 fluid is drawn into the pump l8.

The nozzle 25 includes a body member 29 flat.

Formed within the body member 29 is a transverse iiuid passage 33, of a substantially T-shape, comprised of a threaded inlet section 34, open to sleeve member 31 formed with seats 38 at'their outer ends for seating engagement with jet ball members 39. The ball members 39are yieldably maintained against the seats 38 by a common coil spring ll arranged in compression therebetween, and located within the outlet sections 39. Thus by inserting a pin or like member within the jet ball passages 40, which extend diametrically of the ball members 39, the ball members are movable to an adjusted position and then maintained in such adjusted positions by the action of the spring 9!.

The rear end 39 e and 6) is formed with an upright transverse groove 2 arranged in a parallel relation with the fluid inlet section 34. The groove 4?. has its lower end 43 open to the bottom side of the body member 29 and its upper end 94 closed and of a substantially semi-circular contour in shape. The side-wall of the groove 42 is formed with a continuous undercut portion 99 of a V-shape in transverse cross-section so that the outer edge 91 of the groove 92 overhangs its inner edge 43. As best appears in Fig. 6, the undercut portion 40 is continuous even to extending about the closed end 5% of the groove 32.

In. the mounting of the nozzle on the windshield dividing strip i! there is provided a selftapping metal screw d9 (Figs. 8 and i) which is threadable within an opening 55 formed in the dividing strip H to a position such that its head member 52 is projected forwardly from the front edge of the dividing stri i i. A rubber washer 59 is arranged between the head member 52 and thedividing strip H.

The head member 52 is of a usual conical shape and corresponds to the shape of a transverse cross section through the groove 42 and undercut portion 58 with the innerside 59 of the undercut id, as best appears in Figs. 4 and 6, being in the plane of the bottom wall 55 of the groove 32. With the fluid supply line 27, which is of a substantially rigid construction, threadably connected with the body member 29 at the fluid inlet section 34, the nozzle structure is positioned adjacent to the parting strip il, end 03 of the groove 92 above the head member 52 of the screw 99. On a downward movement of the head member 29 the screw head member 92 is slidably received within the groove 42 to a 1 stop position defined by the engagement of the head member 52 with the closed end 59 of the groove 42 so that the under-cut dB at the closed end 59 constitutes a receivin pocket for the head member 52, whereby the nozzle is supported against downward movement relative to the screw 99.

On connection or" the fluid supply tube 21 with the cowl 12, as indicated at 58, the nozzle 25 is maintained against movement upwardly relative to the screw 99. It is seen, therefore, that the connection of the fluid supply line 21' between the cowl l2 and body member 29 constitutes of the body member 29 (Figs,

with the lowera looking or stop means for holding the head member 52 of the screw 49 within its receiving pocket formed in the body member 29. As a result the body member 29 is positively held against up and down movement relative to the screw 49, with the rubber washer 53 acting to yieldably hold the body member 29 against movement longitudinally of the screw 49.

From a consideration of the above description, it is seen that the invention provides a nozzle structure which is of a simple and compact construction and readily mountable on the dividing strip H and within the transverse dimensions thereof, by a simple inserting action of the screw member head 52 within the lower open end 43 of of the groove '42.

Although the invention has been described with respect to a preferred embodiment thereof, it is to be understood that it is not to be so limited since changes can be made therein which are within the full intended scope of this invention as defined by the appended claim.

I claim:

' For use with a vehicle which includes a nozzle supporting member, a windshield clearing system including a nozzle, means for mounting the nozzle on said supporting member including a body member for said nozzle formed with a transverse groove in one end thereof, with said groove being open at one end to one side of said body member and having the other end thereof closed, with the side walls of said groove being formed with a continuous under cut portion, a screw adapted to be threaded into said supporting member and having a head portion of a shape to be received within said groove in contact engagement with the walls of said under cut portion to a position within the closed end of said groove, and means including afluid supply line for said nozzle attached to said body member so as to hold said head portion within the closed end of said groove.
